[0054] According to some embodiments, the first sub-adhesive
portion AD1 is attached, to a bottom surface of each of the first,
second, and third cap portions CP1, CP2, and CP3. An adhesive
strength of the first sub-adhesive portion AD1 is greater than that
of the second sub-adhesive portion AD2, as will be described in
more detail with reference to FIG. 6.
[0055] FIG. 5 is an enlarged plan view of a cap of FIG. 2 that is
disposed on a rear surface of a window. FIG. 6 is a sectional view
taken along line I-I' of FIG. 5.
[0056] Referring to FIGS. 5 and 6, according to some embodiments,
the cover MHM includes a first cover MHM1 in which the holes MH are
defined, and a second cover MHM2 that extends from the first cover
MHM1. The first cover MHM1 is inserted into the third hole H3, and
the second cover MHM2 is disposed on a portion of the rear surface
BS of the window W adjacent to the third hole H3.
[0057] According to some embodiments, the first cover MHM1 includes
a first sub-cover MHM1_1 which the holes MH are defined, and a
second sub-cover MHM1.sub.13 2 that extends from the first
sub-cover MHM1_1. The first sub-cover MHM1_1 has a flat shape and
is positioned at a bottom of the third hole H3.
[0058] According to some embodiments, the second sub-cover MHM1_2
extends from an end of the first sub-cover MHM1_1 and extends in
the third direction DR3. The second sub-cover MHM1_2 is disposed on
an inner side surface of the third hole H3, and the second cover
MHM2 extends from a top portion of the second sub-cover MHM1_2.
[0059] According to some embodiments, the strengthening portion ST
is disposed on the second cover MHM2 and extends to CONT1 a top
surface of the second sub-cover MHM1.sub.13 2 as well as an upper

The side surface of the second sub-cover MHM1_2 is disposed on an
inner side surface of the third hole 113. The strengthening portion
ST is formed of stainless steel and reinforces the cover MHM.
[0060] According to some embodiments, the first cap portion CP1 is
disposed on the first sub-cover MHM1.sub.13 1 and the strengthening
portion ST to cover or close the holes MH. The first cap portion
CP1 is attached to a top surface of the strengthening portion ST by
the adhesive member AD below the first cap portion CP1.
[0061] According to some embodiments, the second cap portion CP2 is
disposed on the first protection film PF1, and the third cap
portion CP3 is disposed on the second protection film PF2. The
second and third cap portions CP2 and CD3 are respectively attached
to the first and second protection films PF1 and PF2 by the
adhesive members AD below the second and third cap portions CP2 and
CP3, respectively.
[0062] In some cases, positions of the first and second protection
films PF1 and PF2 on the rear surface BS of the window W can be
changed by an external force. According to some embodiments of the
inventive concept, the second and third cap portions CP2 and CP3
are disposed on the first and second protection films PF1 and PF2
to more tightly fix the first and second protection films PF1 and
PF2. Accordingly, the first and second protection films PF1 and PF2
can be prevented from being deformed or warped.
[0063] The cap CP can be misaligned and become attached to a
position outside a normal region. In this case, it may be necessary
to detach the cap CP from the misaligned position. According to
some embodiments, the first sub-adhesive portions AD1 of the
adhesive members AD are attached to bottom surfaces of the first,
second, and third cap portions CP1, CP2, and CP3, and the second
sub-adhesive portions AD2 are attached to top surfaces of the first
and second protection films PF1 and PF2 and a lop surface of the
strengthening portion ST.
[0064] According to sonic embodiments, when an adhesive strength of
the second sub-adhesive portion AD2 is greater than that of the
first sub-adhesive portion AD1, if the cap CP detaches, the
adhesive members AD detach from the first, second, and third cap
portions CP1, CP2, and CP3 while being attached to the top surfaces
of the first and second protection films PF1 and PF2 and the
strengthening portion ST.
[0065] In some embodiments, an adhesive strength of the first
sub-adhesive portion AD1 is greater than that of the second
sub-adhesive portion AD2. Thus, even when the cap CP detaches from
the first and second protection films PF1 and PF2 and the
strengthening portion ST, the adhesive members AD does not detach
from the first, second, and third cap portions CP1, CP2, and
CP3.
[0066] According to some embodiments, the third cap portion CP3
includes a first sub-cap portion CP3.sub.13 1, a second sub-cap
portion CP3_2, and a third sub-cap portion CP3_3. The first sub-cap
portion CP3_1 and the second sub-cap portion CP3_2 are spaced apart
from each other in the first direction DR1 and extend in the second
direction DR2. The third sub-cap portion CP3_3 extends in the first
direction DR1 and extends from top portions of the first and second
sub-cap portions CP3_1 and CP3_2.
[0067] According to some embodiments, the second holes H2 include a
first sub-hole H2_1 and a second sub-hole H2_2 that are spaced
apart in the first direction DR1. The first sub-cap portion CP3_1
overlaps the first sub-hole H2_1, and the second sub-cap portion
CP3_2 overlaps the second sub-hole H2_2. The third cap portion CP3
is not provided between the first sub-hole H2_1 and the second
sub-hole H2_2.
[0068] According to some embodiments, a QR code can be provided
between the first sub-hole H2_1 and the second sub-hole H2_2 of the
window W. The QR code provides detail information of the window W,
such as, about a manufacturer, a manufactured date, or a size of
the window W. The detail information on the window W can be
obtained by scanning the QR code in a process of fabricating a
display device. Since the third cap portion CP3 is Trot provided
between the first sub-hole H2_1 and the second sub-hole H2_2 the QR
code is not obscured by the third cap portion CP3, and thus, it is
possible to normally scan the QR code.
[0069] According to some embodiments, a process of fabricating a
display device includes assembling the window WM with the display
panel. The window WM is moved toward the display panel to assemble
the window WM while maintaining the front protection film FPF, the
first and second protection films PF1 and PF2, and the cap CP that
are attached to the window W. The first, second, and third holes
H1, H2, and H3 are closed by the front protection film FPF on the
front surface FS of the window W, and the first and second holes H1
and H2 are closed by the first and second protection films PF1 and
PF2 on the rear surface BS of the window W.
[0070] According to some embodiments, the third hole H3 is
substantially closed by the first cap portion CP1 disposed on the
rear surface BS of the window W. For example, the holes MH in the
third hole H3 are closed by the first cap portion CP1. Since the
first and second holes H1 and H2 and the holes MH are closed,
contamination materials are prevented from entering the first and
second holes H1 and H2 and the holes MH. Thus, when the window WM
and the display panel are assembled, the display panel is prevented
from being contaminated by contamination materials in the first and
second holes H1 and H2 and the holes MH.
[0071] According to some embodiments, the window WM is transported
into a chamber for the assembling process, the front protection
film FPF, the first and second protection films PF1 and PF2, and
the cap CP of the window WM are removed, and then, the window W is
assembled with the display panel.
[0072] in a window WM according to some embodiments of the
inventive concept, the protection films FPF, PF1, and PF2 and the
cap CP close the first and second, holes H1 and H2 and the holes
and it is possible to prevent contamination materials from entering
the first and second holes H1 and H2 and the holes MH.
[0073] FIGS. 7 to 12 illustrate cap members according to some
embodiments of the inventive concept.
[0074] Hereinafter, cap members CP_1-CP_5 according to some

CP_3. For example, as shown in FIG. 10, the cap CP_3 includes the
first cap portion CP1, the first sidewall portion SW1, and the
second sidewall portion SW2 of FIG. 5. In this case, the cap CP_3
is locally disposed on the cover MHM to cover the holes MH.
[0082] Referring to FIG. 11, according to some embodiments, an
outer side surface of a first sidewall portion SW1' and an outer
side surface of a second sidewall portion SW2' of the cap CP_4 have
a rounded shape. Except for this, other elements of the cap CP_4
have substantially the same features as the cap CP described with
reference to FIGS. 5 and 6.
[0083] According to some embodiments an inner side surface of the
first sidewall portion SW1' and an inner side surface of the second
sidewall portion SW2' face each other. The outer side surface of
the first sidewall portion SW1' is opposite to the inner side
surface of the first sidewall portion SW1', and the outer side

connection portions between the first sidewall portion SW1 and the
second cap portion CP2, and between the second sidewall portion SW2
and the third cap portion CP3, have a step structure. In the case
where, as shown in FIG. 11, the outer side surface of the first
sidewall portion SW1' and the outer side surface of the second
sidewall portion SW2' are rounded, connection portions between the
first sidewall portion SW1' and the second cap portion CP2 and
between the second sidewall portion SW2' and the third cap portion
CP3 are thicker than with the step structure shown in FIG. 6.
[0085] In this case, according to some embodiments, even if an
external force is exerted on the cap CP_4 as depicted by the dotted
line of FIG. 11, the cap CP_4 is strong enough to resist the
external force. Thus, the cap CP_4 is not deformed by the, external
force.
[0086] Referring to FIG. 12, according to some embodiments, the cap
CP_5 further includes a first extended portion EX1 and a second
extended portion EX2 disposed on the first cap portion CP1. The

same features as the cap CP of FIGS. 5 and 6.
[0087] According to some embodiments, the first cap portion CP1 has
a rectangular shape whose long sides are parallel to the first
direction DR1 and whose short sides are parallel to the second
direction DR2, and the first and second extended portions EX1 and
EX2 are provided on the long sides of the first cap portion CP1. In
this case, even if an external force is exerted on the cap CP_5 as
depicted by the dotted line of FIG. 11, the first cap portion CP1
is strong enough to resist the external force. Thus, the first cap
portion CP1 is not deformed by the external force.
[0088] According to some embodiments, the cap CP_5 of FIG. 12 has
substantially the same features as those of the first and second
sidewall portions SW1' and SW2' of FIG. 11, described above, the
first, second, and third cap portions CP1, CP2, and CP3 extends
from each other by the first and second sidewall portions SW1 and
SW2, but embodiment- of the inventive concept are not limited
thereto. For example, the first, second, and third cap portions
CP1, CP2, and CP3 do not extend from each other by the first and
second sidewall portions SW1 and SW2. That is, the first, second,
and third cap portions CP1, CP2, and CP3 can be separated from each
other.
[0089] In a window according to some embodiments of the inventive
concept, protection films and a cap are used to close not only
holes that expose a sensor and a camera but also holes that expose
a speaker, and thus, it is possible to prevent contamination
materials from entering the holes and the holes.
[0090] While exemplary embodiments of the inventive concepts, have
been particularly shown and described, it will be understood by one
of ordinary skill in the art that variations in form and detail may
be made therein without departing from the spirit and scope of the
attached claims.
